This book summarizes recent advances made in the biophysics, biochemistry, and molecular biology of the enzyme known as Photosystem I, the light-induced plastocyanin: ferredoxin oxidoreductase. The volume provides a unique compilation of chapters that includes information highlighting controversial issues to indicate the frontiers of research and places special emphasis on methodology and practice for new researchers.
“Photosynthesis: Plastid Biology, Energy Conversion and Carbon Assimilation” was conceived as a comprehensive treatment touching on most of the processes important for photosynthesis. Most of the chapters provide a broad coverage that, it is hoped, will be accessible to advanced undergraduates, graduate students, and researchers looking to broaden their knowledge of photosynthesis. For biologists, biochemists, and biophysicists, this volume will provide quick background understanding for the breadth of issues in photosynthesis that are important in research and instructional settings. This volume will be of interest to advanced undergraduates in plant biology, and plant biochemistry and to graduate students and instructors wanting a single reference volume on the latest understanding of the critical components of photosynthesis.
An Introduction that describes the origin of cytochrome notation also connects to the history of the field, focusing on research in England in the pre-World War II era. The start of the modern era of studies on structure-function of cytochromes and energy-transducing membrane proteins was marked by the 1988 Nobel Prize in Chemistry, given to J. Deisenhofer, H. Michel, and R. Huber for determination of the crystal structure of the bacterial photosynthetic reaction center. An ab initio logic of presentation in the book discusses the evolution of cytochromes and hemes, followed by theoretical perspectives on electron transfer in proteins and specifically in cytochromes. There is an extensive description of the molecular structures of cytochromes and cytochrome complexes from eukaryotic and prokaryotic sources, bacterial, plant and animal. The presentation of atomic structure information has a major role in these discussions, and makes an important contribution to the broad field of membrane protein structure-function.
Chloroplast development is a key feature of leaf developmental program. Recent advances in plant biology reveal that chloroplasts also determine the development, the structure and the physiology of the entire plant. The books, published thus far, have emphasized the biogenesis of the organelle, but not the events associated with the transformation of the mature chloroplast to the gerontoplast during senescence. This book, with 28 chapters, is unique because it describes how the chloroplast matures and how it is subsequently transformed to become the gerontoplast during senescence, a process required for nutrient recycling in plants. This book includes a state-of-the-art survey of the current knowledge on the regulation and the mechanisms of chloroplast development. Some of the chapters critically discuss the signaling process, the expression potential of plastid DNA, the interaction of cellular organelles, and the molecular mechanisms associated with the assembly and the disassembly of organellar complexes and finally the modulation of chloroplast development by environmental signals.
There are currently intense efforts devoted to understand plant respiration (from genes toecosystems) and its regulatory mechanisms; this is because respiratory CO2 productionrepresents a substantial carbon loss in crops and in natural ecosystems. Thus, in addition tomanipulating photosynthesis to increase plant biomass production, minimization ofrespiratory loss should be considered in plant science and engineering. However, respiratorymetabolic pathways are at the heart of energy and carbon skeleton production and therefore, itis an essential component of carbon metabolism sustaining key processes such asphotosynthesis. The overall goal of this book is to provide an insight in such interactions aswell as an up-to-date view on respiratory metabolism, taking advantage of recent advancesand concepts, from fluxomics to natural isotopic signal of plant CO2 efflux. It is thus a nonoverlapping,complement to Volume 18 in this series (Plant Respiration From Cell toEcosystem) which mostly deals with mitochondrial electron fluxes and plant-scale respiratorylosses.
The first dedicated new work since 1991, this book reviews recent progress and current studies in the chemistry, metabolism and spectroscopy of chlorophylls, bacteriochlorophylls and their protein complexes. Also discussed is progress on the applications of chlorophylls as photosensitizers in photodynamic therapy of cancerous tumours, and as molecular probes in biochemistry, medicine, plant physiology, ecology and geochemistry. Each section offers an introductory overview followed by concise, focused and fully-referenced chapters written by experts.
Respiration in Archaea and Bacteria summarizes the achievements of the past decade in the biochemistry, bioenergetics, structural and molecular biology of respiratory processes in selected groups of prokaryotes. It includes a series of Chapters providing an extensive coverage of the respiratory membrane-bound bacterial redox complexes and enzymes; it also covers evolution of respiration, cytochrome c biogenesis, bacterial haemoglobins, and oxidases as redox sensors.
Current Topics in Bioenergetics, Volume 16 focuses on photosynthetic electron transfer, ATP-synthesizing reactions, and nitrogen fixation. It looks at the application of biochemistry and biophysics in the exploitation of gene isolation, sequencing, and analysis of structure and function. It also reviews photosystems I and II and electron transfer reactions in eukaryotic chloroplasts of more modern plants as well as in photosynthetic membranes of the very ancient cyanobacteria. Organized into seven chapters, this volume begins with an overview of photosystems I and II. Then, it discusses the ATP synthesis in chloroplasts, with special attention given to the genes and their protein products th...
This publication is based upon work from COST Action ’16203 MARISTEM Stem cells of marine/aquatic invertebrates: from basic research to innovative applications’, supported by COST (European Cooperation in Science and Technology).

Air quality has a direct influence on health, welfare and production performance of livestock as the high concentrations of noxious gases, dust and airborne microorganisms are likely to reduce production efficiency and the general welfare of farm animals. Long term exposure to particulates in livestock buildings might also affect the respiratory health of farm workers. Dust in animal buildings contains many biologically active substances such as bacteria, fungi, endotoxins and residues of antibiotics (as a result of veterinary treatments) that are suspected to be hazardous to human health. Furthermore, air pollutants emitted from livestock buildings can reduce air, water and soil quality and...
